Each pair of connectionlocations 91 (one from each row) would be linked to one of the fibers ofcable 300 in FIG. 13. Other splitters, such as one-by-fours, etc. may beused, as desired.

In FIGS. 15 and 16, a splice 360 to a wave division multiplexer (WDM)361 allows for module 24 to have wavelength division multiplexingfunctions associated with connection locations 91. A “dense” wavedivision multiplexer may be used, if desired (DWDM). For themultiplexing function, row 362 of connection locations 91 could serve asthe first wavelength ports, and row 364 could serve as the differentwavelength ports. Each pair of connection locations 91 (one from eachrow) would be linked to one of the fibers of cable 300 in FIG. 15.

FIG. 17 shows just a splicing component 370 so that each fiber of cable300 could be spliced to a fiber leading to one connection location 91.Other passive optical components can be selected as desired to providemodule 24 with the desired function or functions.

Referring now to FIGS. 22 and 23, blank panels 150, 170 comprisingmodules 23 are shown. Each blank panel 150, 170 includes a generallyplanar front 152, and flanges 154 including holes 158, 160 to enablemounting of the blank modules 150, 170 to frame 22.
